Flowmeter information

Extending the flow meters calibrated range

It’s not an uncommon request. When the enquiry comes in, our client thinks the require range will be 1 to 10, but once installed, it’s clear it should have been 2 – 20. What do we do then? First step It’s unlikely the range can be extended beyond the flow meter maximum rate flow rate. […]

What is Linearisation?

what is Linearisation, and why do you need it? We take a look into the world of Linearisation and why you need it for your flow measurement solutions. Linearisation is a process that enhances the accuracy of any repeatable flow meter. A standard calibration of our VFF flow meter will involve 10 calibration points. These […]

What’s in a typical flow meter datasheet?

A typical datasheet relating to a flowmeter is given as below – this one is based on a NORSOK format: This one is for the same meter but based on an ISA format (a version used by Litre Meter which uses S20.25 as it’s base): Norsok: This is an approximate layout, typified by NORSOK. 1 General 1.01 […]

High Pressure Flow Meters – How Do We Test Them?

At Litre Meter we are industry leaders in producing high pressure flow meters. But how do we ensure the pressures our customers request, can be safely achieved? Pressure Ratings Generally, the pressure ratings for our flowmeters depend on the rating of the connection. Within our standard line of VFF flow meters, we provide “Medium Pressure” […]

Rotary Piston

A look at the rotary piston flow meter range and how the range of flow meters work. Positive displacement flow meters, also known as PD meters, measure volumes of fluid flowing through by counting repeatedly the filling and discharging of known fixed volumes. A typical positive displacement flowmeter comprises a chamber that obstructs the flow. […]
